Introduction - EverFocus EPN4122 User Manual

1. Introduction

The EPN series is a high-performance IP speed dome supporting up to 22x optical-zoom and dual streams
from H.264 and MJPEG. The series comes in two types: outdoor (EPN4122 / 4220) and indoor (EPN4122i /
4220i). Equipped with a weather-proof (IP66) housing, the outdoor models meet a wide variety of needs
for outdoor surveillance.
EverFocus IP speed dome provides Auto Tracking function to detect movement in the camera's field of
view; and variable pan/tilt speeds ranging from 360° per second to 0.01° per second with 0.1° position
accuracy for fast and accurate monitoring. A maximum of 256 preset points can be configured for precise
location of target areas. Features like 360° endless rotation, 16 tour sequences, 4 patterns are all provided.
The IP speed dome also features Wide Dynamic Range (WDR) function, which can provide clear images
even under back light circumstances where intensity of illumination can vary excessively. The DNR (Digital
Noise Reduction) function is designed for reducing the noises in the images, allowing the camera to better
distinguish between real motion and image noise, and thus results in a possibility to store more video
evidence on the connected storage devices.
A built-in micro SDHC card slot is also provided. You can power the camera by connecting the camera to a
24 VAC power supply. Since the EPN series IP speed dome conforms to ONVIF / PSIA for compatibility with
other network video devices, it interoperates with a wide variety of hardware and software systems. You
can also use EverFocus Mobile Applications to remotely view the live views of the cameras through your
handheld devices; or use EverFocus CMS to remotely manage multiple IP devices connected on the
network.
